Objective To investigate the imaging and clinical characteristics of reversible posterior leukoencephalopathy syndrome (RPLS). Method The imaging and clinical data of 6 patients with RPLS were analyzed retrospectively. Results CT and MRI examination in 6 patients revealed symmetry white matter lesions of occipital lobe in 4 patients, widely white matter edema of fronto-parietal subcortieal white matter in 4 patients, mesencephal and thalamencephal involved in 1 patient, caudate nucleus involved in 1patient. Venous sinus thrombosis was not found in 2 patients of pregnancy-induced hypertension syndrome with magnetic resonance intravenous angiography.All patients were given active treatment,including controlling blood pressure and seizure disorder,dehydration and supporting therapy.The symptom of 5 patients disappeared. One patient left with hemiparesis of right body.Nobody died. Condusion Diagnosis of RPLS isn't difficult as long as clinical history,imaging characteristics and clinical tetrad in the patients of hyperten-sion,eclamptism or renal inadequacy is combined to consider.

Objective To investigate the relationship between angiotensin 1-converting enzyme(ACE)inserting/defaulting(I/D)gene polymorphisms and the carotid intima-media thickness(CCA-IMT)in patients with type 2 diabetes(T2DM).Methods The polymorphisms of ACE(I/D)was determined by polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP)method and the CCA-IMT was assessed using non-invasive high resolution B-mode ultrasonography in 120 T2DM in Han's population of Dongguan city.The data were analyzed by Logistic regression to explore the independent and significant risk factors for CCA-IMT increase in type 2 diabetic patients.Results The DD genotype were significantly more common in diabetic patients with CCA-IMT increase than in those without it(F=10.164,P=0.006);Logistic regression analysis showed that DD genotype,age,male gender and essential hypertension contributed significantly to the CCA-IMT increase in type 2 diabetic patients(OR=3.689,1.054,1.562,respectively,P

Objective To evaluate the diagnostic values of MRA,TCD and ultrasonography in carotid territory transient ischemic attacks (TIAs). Methods 42 patients with carotid territory TIAs were examined by MRA, TCD and ultrasonography. Results MRA showed abnormalities of carotid arteries in 12 cases (28.6%) and abnormalities of intracranial arteries in 32 cases (76.2%). 8 cases presented abnormalities both in carotid arteries and intracranial arteries. Abnormalities of intracranial arteries were detected by TCD in 30 cases (71.4%) and abnormalities of carotid arteries were detected by ultrasonography in 16 cases (38.1%).Conclusion MRA, TCD and ultrasonography are useful in the evaluation of etiological factors of carotid territory TIAs.

Objective To explore the neuropsychological disorders and its mechanism of tuberothalamic artery infarction.Methods Clinical data of 9 patients with tuberothalamic artery infarction were analyzed retrospectively.Results Primary clinical manifestation of 9 patients were abulia,behavior disorders,thalamic aphasia,left spatial neglect,visual space function disorders,memory disorders.All of them,however,did not exist brain nerves lesion and disorders of motor and sense.Conclusion The clinical manifestation of tuberothalamic artery infarction patients are mainly neuropsychological disorders.

ObjectiveTo analyze the mental status of the patients with irritable bowel syndrome (IBS).MethodsSixty IBS patients were evaluated with Self Rating Anxiety Scale (SAS), Self Rating Depression Scale (SDS), Symptions Check List-90 (SCL-90) and self-edited scale.ResultsThe primary causes of mental disorder of IBS patients were the stress events and lacking knowledge for IBS; the average SAS scores of sixty IBS patients were 52.32±10.19, SDS scores were 54.90±11.70; the average scores of SAS and SDS in the groups of midlife and young people were significantly higher than that in the group of agedness ( P<0.05). The total scores of SAS and SDS were not significantly difference among the patients with different culture level and sex ( P>0.05); except the scores of crankiness and opposition, the average SCL-90 scores of the sixty IBS patients were significantly higher than the normal ( P<0.05).ConclusionIBS relates to mental status and stress, proper mental intervention can ease the symptom and improve the quality of the living.

ObjectiveTo investigate the efficacy and safety of aripiprazole in treating schizophrenia with clozaping as control.Methods70 cases with schizophrenia were randomly divided into the experimental and control group with 35 cases in each group.The effectiveness and safety were evaluated with positive and negative syndrome scale and treatment emergent symptoms scale before and at the ends of week 1,2,4,6,and 8 after starting treatment respectively.ResultsThere was no significant difference in effectiveness between two groups.However,the score reduce rates about cognitive factors and negative symptoms of the aripiprazole group was better than that of the clozaping group(P<0.05).The main side effects in aripiprazole group were mild headache,anxiety,insomnia and etc.ConclusionAripiprazole is an effective and safe neuroleptic,specifically in improving cognitive function and negative symptoms.

Objective: To investigate the clinicopathologic characteristics and etiological factors of cervical cancer in young Uygur women in Xinjiang.Methods" We reviewed 350 cases of young Uygur females diagnosed with cervical cancer in our hospital during 1998-2007.The patients were divided into two groups according to their admission time (1998～2002 group and 2003～2007 group).Results: The incidence of cervical carcinoma among yong Uygur women was 12.9% in the 1998-2002 group and 10.3% in the 2003-2007 group.The first symptom was vaginal contactive bleeding.In both groups, most patients were peasants, but the percentages of highbrow was higher in the 2003-2007 group.Patients in the 2003～2007 group were of older age at first marriage and had lower rate of abortion.There was no significant difference in histological type between the two groups.However, patients in the 2003-2007 group presented with much earlier stage of cervical cancer and 56.9% of them were of stage Ⅱ disease, compared with 18.1% in the 1998-2002 group (P<0.05).Squamous cell carcinoma was the dominant histological type.Conclusion: The incidence of cervical carcinoma in young Uygur women tends to decrease due to screening and advocation of late marriage, less reproduction in remote rural areas of Xinjiang.

876 women with polycystic ovary syndrome (PCOS) were collected from Sep 2004 to Oct 2006. Among them 800 patients with polycystic ovary ultrasound image belonged to group A; the other 76 women without polyeystic ovary ultrasound image belonged to group B. As compared with group A, group B showed significantly higher hirsutism scores, serum testosterone, cholesterol, and lower density lipoprotein. Significantly higher prevalences of diabetes mellitus and hypertension appeared in the first degree relatives in group B than in group A.

Objective To investigate the difference in ocular surface microbiota between dry eye patients and healthy subjects,and discuss the role of microbiota in dry eye.Methods Twenty cases of dry eye patients and 90 cases of healthy subjects were collected in the PLA General Hospital and Zhongshan Ophthalmic Center.The samples of conjunctiva impression cytology were collected from all subjects,and then metagenomic shotgun sequencing was performed following the DNA extraction.The differences in alpha diversity and metabolic pathways of the ocular surface microbiota between dry eye patients and healthy subjects were evaluated.Results There was no significant difference in alpha diversity of the microbial community between dry eye patients and healthy subjects (P =0.13).However,an increase of 15 species and a decrease of 10 species were detected on the ocular surface of dry eye patients.The enriched antibiotic resistance genes in dry eye patients were more than healthy subjects.Conclusion Although the alpha diversity of the microbial community on ocular surface between dry eye patients and healthy subjects are not distinguishable,a significant difference could be found in relative abundance and metabolic pathways,suggest that these specific microbiome may be related to the pathogenesis and disease progression of dry eye.

Objective To investigate the relationship between the bacterial vaginosis and 8 putative periodontal pathogen infection.Methods A total of 48 patients with bacterial vaginosis were collected and 47 healthy female patients were selectedin the control group.Vaginal secretion and subgingival plaque were obtained from the study group and the control group.The presence of Porphyromonasgingivalis (P.g),Tannerella forsythia (T.f),Treponemas denticola (T.d),Prevotell intermedia (P.i),Prevotella nigrescen (P.n),Peptostreptococcus micros (P.m),Fusobacteriumnucleatum (F.n) and Campylobacterrectas (C.r) was detected by DNA extraction and PCR method.Simultaneously,all the patients underwent a clinical periodontal examination of the teeth in community periodontal index,including plaque index (PLI),bleeding on probing (BOP),probing depth (PD) and clinical attachment loss (CAL) Results The prevalence of periodontal disease,PLI,BOP and CAL in the study group was significantly higher than in the control group (P＜0.05) and the PD had no statistically significant difference between the 2 groups (P＞O.05).The 2 groups were both detected 8 putative periodontal pathogens in the vaginal secretion and the subgingival plaque samples.The detection ratio of T.dfrom both the vaginal secretion and subgingival plaque samples was significantly higher in the study group than that in the control group (P ＜0.05),and other 7 pathogens showed no statistically significant difference (P ＞0.05) Conclusion The prevalence of periodontal disease was higher among the bacterial vaginosis patients.The 8 putative periodontal pathogens were normal flora in the subgingival plaque and vaginal secretion.Td might be relevant to the pathogenesis of bacterial vaginosis.
