In total, 4006 women aged 25 -65 years at Qiaozi Town, Huairou District, Beijing were screened for cervical cancer during April to June, 2009. Results showed that 54. 52% of the women screened suffered from varied gynecological illness, highest in those aged 30 - 34 years ( 80. 90% ) and lowest in those aged 50 -54 years. The top three gynecological morbidity among them were cervicitis (34. 77% ), virginities ( 12. 88% ) and uterine leiomyoma (8. 34% ). Precancerous lesions in 12 women,endometrial cancer in one woman and cervical cancer in one woman were detected by cervical cytological examinations.

ObjectiveTo study the role of the myenteric plexus (ENS) nitrergic neurons in type 2 diabetic rats with gastroparesis.MethodsThiry male 8-week-SD rats were randomly divided into control group (CON),type 2 diabetic group (DM),insulin-treated group ( INS ) and insulin-lipoie acid group( LA ),each 15.The rats were sacrificed at 16 weeks after diabetic model established,the stomach relative residual rate of pigmented was measured and the protein content of neuronal nitric oxide synthase (nNOS) was evaluate,the level of malondialdehyde (MDA) and superoxide dismutase (SOD),were measured,the the morphological changes of gastric antrum nitrergic neurons was observed.ResultsCompared with CON group,gastric motility,gastric antrum nitrergic neuron count,T-SOD and CuZn-SOD,and were significantly decreased in DM group ( P ＜0.05).Compared with the CON group,DM group gastric antrum nitrergic neurons nNOS expression decreased,while MDA levels significantly increased ( P ＜ 0.05 ).Compared with DM group,INS group and LA group has significantly rapider gastric motility than that of DM group ( P＜ 0.05 ),the neuron counting markly increased in nitrergic neuron of gastic sinus ( P ＜ 0.05 ),increased expressions of nNOS in gastric sinus,while still lower than control group( P ＜0.05).compared with the INS group,antrum nitrergic neuron counts of LA group significantly increased ( P ＜ 0.05 ).Conclusion The gastrointestinal dyskinesis of type 2 diabetic rats might be associated with lesions of gastric myenteric plexus nitrergic neuron.Insulin intensive therapy and treated with alpha-lipoic acid as an antioxidant can inhibit the abnormally high levels of oxidative stress,protect gastrointestinal nitrergic neurons,delay the progress of diabetic gastrointestinal motility disorders.Insulin combined with a-lipoic acid treatment is superior to single-use insulin.

Objective To determine the prognosis and risk factors of neonatal cerebral infarction.Methods From January 2002 to December 2010,44 newborn infants were diagnosed with cerebral infarction by imaging examinations at Peking University First Hospital.The neurodevelopmental outcomes of these newborn infants were followed up and evaluated by clinical manifestations,Gesell development scale,cranial imaging,electroencephalogram and auditory evoked potential.Factors related to prognosis were analyzed with single and multi-factor Logistic regression analysis.Results Thirty-eight (86％) cases were followed up,and of these cases,five children died and the results of three were inconclusive due to small age (less than 6 months old).Among the remaining 30 children,neurodevelopmental outcome was normal in 15 cases and abnormal in the remaining 15 cases,thus,the incidence of sequelae was 50％ (15/30) and the mortality rate was 13％ (5/38).Of the 15 abnormal cases,all had cerebral palsy and movement retardation,eight cases had cognitive impairment,eight cases had epilepsy and five had visual impairment.The incidence of large cerebral infarction (more than one lobe) was 14/15,worse cranial imaging outcome (one month after treatment,cerebral infarction lesion still present or had expanded)was 13/15,and severe complications was 8/15 in the newborns with sequelae,which were higher than in those without sequelae (4/15,5/15 and 1/15,respectively) (x2=13.889,8.889 and 7.778,all P＜0.05).Logistic regression analysis showed that large cerebral infarction was a risk factor for sequelae (OR=38.500,95％C1:3.749-395.407,P=0.002),however,worse cranial imaging outcome (OR=8.563,95％CI:0.909-80.683,P=0.061) and severe complications (OR=18.024,95％CI:0.516-630.163,P=0.111) were not risk factors for sequelae.Cerebral infarction with middle cerebral artery injury had a high risk of movement retardation (OR=6.000,95％CI:1.172-3.725,P=0.025),and those with a large cerebral infarction were more likely to have epilepsy (x2=7.273,P=0.010).The incidence of large cerebral infarction in the newborn infants with cognitive impairment was 8/8,which was much higher than in those without cognitive impairment (46％,10/22),thus,infarct area may be related to cognitive ability (x2=7.273,P=0.010).Conclusions Neonatal cerebral infarction might result in many types of sequelae,with motor impairment being the most common form.A large cerebral infarction is more likely to result in abnormal neurodevelopmental outcome.

Objective To understand use of blood pressure-lowering medications and to identify factors contributing to their compliance among hypertensive patients at a community health-care service center under Huairou County Hospital, Beijing to improve community management for hypertensive therapy.Methods Medical records of hypertensive patients who visited Qiaozizhen community health-care service center in Huairou county, Beijing during June 2008 to May 2009 were analyzed and 849 of them were interviewed using a pre-tested, structured questionnaire with most closed ended questions included to understand their use of anti-hypertensive drugs and its related factors. Results In 849 hypertensive patients under community management, 78.92% percent (670/849) took anti-hypertensive drugs, 72.54%percent (486/670) in good compliance with drug treatment, and 29. 63 percent (144/486) under guidance of their general practitioners or visited secondary-care hospitals or above, 62. 14 percent (302/486) took drugs by themselves and 8. 23 percent (40/486) took drugs following advice by their relatives or other hypertensive patients. The most common used drugs in 503 hypertensive patients who could remember names of the drugs included reserpine compound tablets, reserpine and triamterene compound tablets (302/503, 60. 04% ) and calcium-channel blockers ( 181/503,35.98% ). Overall, blood pressure was under control in ( 289/849,34. 04% ) percent of those with community management, and( 189/486, 38. 89% ) percent of them kept in a good compliance, significantly higher than that in those with poor compliance (48/179,26. 82% ) (P =0. 0032). Results of multivariate logistic regression analysis showed that drug compliance associated mainly with complications of hypertension ( OR of 4. 423 and 95% CI of ORs 2. 141 - 9. 137). Conclusions Drug compliance among hypertensive patients is still poor in rural Beijing, most with reserpine compound tablets.It is necessary to pay more attention to health education among hypertensive patients, particularly about when to start drug-taking and how to take drugs in a scientific way-regularly and complying with physicians'prescription.

Objective To investigate the feasibility and accuracy of velocity vector imaging(VVI)to assess strain and strain rate of right ventrieule(RV)during varying myocardial functional states.Methods VVI of the longitudinal RV were recorded in 7 closed-chest anesthetized mongrel dogs from the apical 4-chamber view during 3 different inotropic states.Peak dp/dt from the RV contraction during the right cardiac catheterization,which was used as the gold standard of RV contractility,was obtained simultaneously in each inotropic state.Peak systolic velocities(V), peak systolic strain rates(SR),peak systolic strains(S)at the basal, middle and apical segments of RV free wall and septal from the longitudinal axis were quantitatively measured by using VVI software system respectively.Results The peak systolic strain and strain rate of the longitudinal RV free wall and septal were increased with the infusion of dobutamine and decreased with the infusion of metoprolol.A significant correlation was found between peak RV dp/dt and RV mean strain and mean strain rate(r=0.79, 0.75;P <0.01).Among all RV segments, the peak systolic S,SR of RV basal free wall had the most significant correlation to peak dp/dt (r=0.83,0.78;P<0.01).Conclusions Strain rate imaging drived from VVI could quantitatively and sensitively detect the longitudinal RV contractile function.Peak systolic S and SR determined at the longitudinal RV basal free wall were the strong noninvasive indices of RV contractility.

Diffuse large B-cell lymphoma (DLBCL) is characterized by heterogeneity with respect to morphology, immune phenotype, molecular pathogenesis, clinical presentation and prognosis. With the development of genome and transcriptome sequencing, DLBCL was classified as four subtypes (EZB, BN2, MCD, and N1) or five subtypes (C1-C5). The new molecular pathological typing has a deeper understanding of DLBCL from the levels of genes and molecules which makes the judgment of prognosis more accurate and specific, and it is conducive to the clinical screening of more accurate targeted therapy.

Objective To investigate the risk factors of cerebral infarction in newborns and to provide a theoretic basis for prevention.Methods From January 2002 to December 2010,8840 newborns were admitted into the Neonatology Department of Peking University First Hospital,among which 44 patients were diagnosed as cerebral infarction by review of brain imaging and medical records.These patients were taken as study group,and 175 patients were randomly selected as the control group matched by birthday and gestational age.Risk factors of neonatal cerebral infarction were analyzed by univariate analysis and binary Logistic regression.Results Of 27 352 infants born in Peking University First Hospital,21 infants were diagnosed as neonatal cerebral tnfarction,giving the prevalence of neonatal cerebral infarction of 7 per 10 000 live births (21/27 352).Of the 8840patients in Department of Neonatology,neonatal cerebral infarction accounts for 5.0‰ (44/8840).81.8％ (36/44) of the affected babies were delivered at term.The incidence of hypoxia and polycythemia in study group were 50.0％ (22/44) and 11.4％ (5/44),higher than those in control group [27.4％(48/175) and 2.9％(5/175)],differences were statistical significant (x2 =8.237,OR=2.646,95％CI:1.343-5.211,P=0.004; x2 =5.838,OR=4.359,95％CI:1.203-15.796,P=0.030).Logistic regression showed that hypertensive disorder complicating pregnancy (OR=3.388,95％CI:1.174-9.778,P=0.024),polycythemia (OR=4.319,95％CI:1.136-16.427,P=0.032)and hypoxia (OR =2.860,95％ CI:1.415-5.782,P =0.003) were risk factors for neonatal infarction.Further analysis suggested that the severity of hypoxia (x2 =- 3.470,P =0.001 ) and hypertensive disorder complicating pregnancy (x2=-2.074,P=0.038) had positive correlation with neonatal cerebral infarction.Conclusions Hypertensive disorder complicating pregnancy,polycythemia and hypoxia were risk factors of cerebral infarction,especially when preeclampsia and severe hypoxia occurred.

Objective To explore risk factors of cerebral infarction in newborns by systematic reviews.Methods Case-control studies and case reports on risk factors of cerebral infarction in newborns from January 1997 to December 2011 were collected from database of CNKI,CQVIP,Wanfang Database,PubMed,OVID,Springer,Medline,Science Direct On Site,Besco and MD Consult.Meta analysis was performed on case-control studies with fixed or random effect model by Review Manager 5.0.Constitution ratio of risk factors of cerebral infarction in newborns in case reports was investigated.Results Two hundred and sixty-nine articles were found and among which,36 articles in English were selected for this study.Three case-control studies were found and adopted for meta analysis.Cumulative number of patients and control cases were 80 and 228,respectively.The pooled OR and 95 ％CI of selected factors were as follows:decreased fetal movement [7.10 (2.92-17.24)],abnormal fetal heart rate [4.45 (2.54-7.80)],vacuum delivery [2.99 (1.23-7.25)],resuscitation at birth [(3.14 (1.17-8.46)],premature rupture of membranes [2.40 (0.62-9.29)],cesarean section [2.64 (1.44-4.82)],preeclampsia [3.05 (1.44-6.43)],history of infertility [1.25 (0.18-8.67)],primiparous [1.79 (0.51-6.36)],oxytocin used [2.05 (0.99-4.25)],fetal growth restriction [0.99 (0.47-2.11)],meconium stained amniotic fluid [2.08 (0.94-4.58)],adverse pregnancy history [0.85 (0.43-1.68)] and breech presentation [0.38 (0.10-1.46)].Meta analysis showed that decreased fetal movement,abnormal fetal heart rate,vacuum extraction,resuscitation at birth,cesarean section and preeclampsia were risk factors of neonatal cerebral infarction.Decreased fetal movement,abnormal fetal heart rate and resuscitation at birth suggested that newborns suffered from perinatal hypoxia,vacuum extraction,cesarean section suggested abnormal delivery.It suggested that perinatal hypoxia and abnormal delivery were high risk factors of neonatal cerebral infarction.Among those factors,proportion of abnormal labor,fetal distress and hypercoagulabe state was 31.70％,21.13％ and 20.19％ respectively.Conclusions Abnormal birth,hypoxia,preeclampsia and hypercoagulation state might relate to neonatal cerebral infarction.

ObjectiveTo observe the effects of moxibustion in treating knee osteoarthritis (KOA).MethodTotally105 patients with KOA were randomly divided intoamoxibustion group (n=39), anelectroacupuncture group(n=44) andaCelebrex group (n=22).The three groups were treatedsuccessively for 4 weeks.The visual analogue scale (VAS) score of knee-joint pain and knee-joint function score were observed.ResultSeven days,fourteen days and twenty-eight daysrespectivelyafterthe treatment,theVAS scores of knee-joint pain and knee-joint function scoresweresignificantlydecreased in the three groups (P<0.001). Fourteen days and twenty-eight days afterthe intervention,the knee-joint function scores ofthemoxibustion group and electroacupuncture group weresignificantlyhigherthan those oftheCelebrex group (P<0.05).ConclusionMoxibustion therapy can improve the clinical symptoms and the knee-joint function in patients with KOA,similar to the electroacupuncture group and Celebrex group, and the moxibustion group has better effect in improving theknee-joint functioncompared to the Celebrex group.

Objective To evaluate the utility of MMP9,MPO and sCD40L in detection of the character of coronary artery plaque.Methods From April 2008 to January 2010,118 patients from outpatient of Fu Wai Hospital with chest pain were enrolled.All of them underwent 64 Multiple-detector row spiral computer tomography (64-MDCT),the CT value ＜ 130 Hu patients were enrolled in non-calcified plaque group (71 cases),CT value ≥ 130 Hu patients were enrolled in the calcified plaque group (47 cases).Ninty healthy volunteers were selected as the control group.Enzyme-linked immunosorbent assay (ELISA) was used to detect the levels of serum markers,including MMP9,MPO and sCD40L.Levels of MMP9,MPO and sCD40L of each group were compared.ROC curve was used to evaluate the sensitivity and specificity of the markers in diagnosis of non-calcified plaque.Results MMP9,MPO and sCD40L levels of non-calcified were ( 762.25 ± 368.71 ),[ 844.10 (582.00 - 1220.70) ],(9.37 ± 3.15) μg/L,higher than the healthy control group (342.70 ± 178.53),[426.35 ( 283.20 - 592.00) ],(6.55 ± 2.96) μg/L and calcified plaque group ( 483.12 ± 219.09 ),[ 469.00 ( 302.45 - 723.55) ],( 7.24 ± 2.86) μg/L The difference was statistically significant ( F =42.47,H =50.28,F =17.94,all P ＜ 0.01 ). Areas of MMP9,MPO and sCD40L under the ROC curve to predict non-calcified plaque were 0.854,0.792,0.751 respectively,when the identification threshold for non-calcified plaque were 510.13,537.82,7.05 μg/L respectively,the diagnostic sensitivity was 80％,80％,80％ respectively,and specificity was 80％,67％ and 55％ respectively.Conclusion The serum MMP9,MPO and sCD40L levels can help to determine the　character of coronary plaque.
