Objective  To investigate the clinical features of autoimmune glial fibrillary acidic protein (GFAP) astrocytopathy.  Methods  We collected and analyzed the clinical and laboratory data and obtained the clinical characteristics of diagnosis and treatment from fifteen patients with positive GFAP antibody tested by cerebrospinal fluid and diagnosed autoimmune GFAP astrocytopathy by the multi-centers.  Results  The mean age of the first onset of autoimmune GFAP astrocytopathy was 39.73 years old (range 4-65 years), with no significant gender difference. In terms of clinical manifestations, we found the whole brain symptoms including abnormal mental behavior, disturbance of consciousness, epileptic attack accounting for more than 50, , meningitis accounting for 66.7%, myelitis (53.3%), limb tremor (53.3%), vision loss (33.3%); systemic symptoms including fever(100%) and fatigue(86.7%). 46.7% of patients were initially diagnosed with tuberculous meningoencephalitis and were treated with diagnostic antituberculous therapy. The MRI showed 46.7% of patients showed brain linear perivascular radial gadolinium enhancement in the white matter perpendicular to the ventricle.  Conclusions  Autoimmune GFAP astrocytopathy are acute or subacute dieases and the main clinical features include encephalitis, meningitis, myelitis and optic neuritis. They are likely to be misdiagnosed as tuberculous meningoencephalitis and can manifest progressive loss of consciousness in early phase, which is even life threatening.

Objective To explore the feasibility of in vitro biological soft tissue imaging by using synchrotron radiation phase contrast CT.Methods Three samples of resected human cardia,two samples of resected human esophageal carcinoma and esophagus,as well as two samples of middle cerebral artery tissue extracted from corpses were fixed and airdried at room temperature for synchrotron radiation phase contrast CT imaging.The images of soft tissue structures were observed and compared with pathological findings.Results The images of synchrotron radiation phase contrast CT showed three-layer structure of cardia and esophagus,mucous,submucosa and muscular layer.The surface of mucous layer was smooth.The images of esophageal carcinoma showed cancerous tissue infiltrating esophageal wall.The wall and lumen of cerebral arteries could be also clearly displayed.Conclusion Synchrotron radiation phase contrast CT imaging can clearly display fine structures of in vitro biological soft tissue.

Objective To study the prevalence and associated factors of loneliness in individuals with speech disability.Methods Using multi-stage stratified random cluster sampling method,170 community-residing ver-bally disabled persons were selected and administered with a general information questionnaire,one single -item loneliness self-rating question and social support scale.A total of 204 study questionnaires were distributed to the subjects;170 subjects(mean age:43.1±13.7 years)completed the survey.Results As high as 46.47% (79/170)of these verbally disabled individuals reported to feel lonely often.Females (OR=2.45),unemployment (OR=2.95), first and second degrees of disability (OR=4.35),co-existence of chronic illnesses (OR=6.50)and low utiliza-tion of social support (OR=2.58)were significantly associated with the increased risk of loneliness in persons with speech disability (P =0.002~0.046).Conclusion Loneliness is highly prevalent in individuals with speech disabili-ty.Verbally disabled persons,who are female,unemployed,severely disabled,and chronically ill and have a low use of social support,are the target population of mental health services.

Objective To investigate the effects of “patient-family-community”health promotion mode on patients with impaired glucose regulation(IGR).Methods Using the function of random case samples in SPSS,we randomly chose an experimental village and a control village respectively from all villages in Zhuqiao of Pudong New Area.Altogether 75 IGR patients who met the requirement were filtered in the two villages. According to the villages they belonging to,39 of them were divided into experimental group and 36 to control group.From March 201 4 to August 201 4, subjects in the experimental group were intervened by“patient-family-community”health promotion mode,while participants in the control group used the regular health guidance.We compared the test score of knowledge-attitude-practice (KAP) questionnaire,family APGAR questionnaire and blood glucose between two groups.Results Relevant indexes of the two groups before intervention showed no difference (P >0.05).After intervention,the knowledge(K),attitude(A)and practice (P)test scores of the experimental group were (8.85 ±1 .31 ),(8.87 ±1 .77)and (6.92 ±2.67),higher than (5.86 ±2.37),(6.78 ±2.92)and (3.89 ±3.02)of the control group(Z =-5.1 89,-3.299,-4.042;P <0.05).The APGAR test scores of the experimental group(7.56 ±1 .90)was higher than(6.47 ±1 .77)of the control group(t =2.571 ,P <0.05).The FPG,2hPG and HbA1 c of the experimental group were (5.86 ± 0.50)mmol/L,(8.02 ±0.72)mmol/L and(5.73 ±0.42)%,which were lower than (6.1 1 ±0.45)mmol/L, (8.60 ±0.97)mmol/L and(5.97 ±0.53)% of the control group (t =-2.293,-2.383,-2.1 70;P <0.05).Conclusions Applying “patient-family-community”health promotion mode can improve the KAP, family function of IGR patients,control their blood glucose better and prevent diabetes.

OBJECTIVETo investigate the expression of prostaglandin transporter (PGT) in colorectal cancer (CRC) tissues and its relationship with clinicopathological features.

METHODSThe mRNA and protein levels of PGT were determined by real-time PCR, Western blot and immunohistochemical methods in cancer tissues and adjacent normal tissue from 80 patients with colorectal cancer and their relationship with clinicopathological features was analyzed.

RESULTSCompared with the adjacent normal tissue of colorectal cancer, the PGT mRNA relative expression (0.57 ± 0.33 vs. 2.33 ± 1.20) and the PGT protein expression in cancer tissues decreased significantly [PGT/GAPDH 0.45 ± 0.16 vs. 0.78 ± 0.23, integral A 718.7 ± 359.4 vs. 10412.0 ± 6423.3, average A 0.03 ± 0.01 vs. 0.12 ± 0.09, all P<0.01]. Lower mRNA and protein expressions of PGT in colorectal cancer were associated with depth of invasion T3 to T4 and TNM stage III( to IIII( (P<0.01), while not associated with gender, age, tumor location and differentiation degree (all P>0.05).

CONCLUSIONExpression levels of PGT mRNA and protein in colorectal cancer tissue are significantly down-regulation. PGT expression is associated with invasion depth and late stages.

OBJECTIVETo assess the efficacy and safety of modified ligation of the intersphincteric fistula tract for simple transsphincteric perianal fistula.

METHODSSeventy patients with simple transsphincteric perianal fistula between October 2012 and January 2014 in our department were prospectively enrolled. According to the random number table, patients were divided into two groups: modified-LIFT group (37 cases, from the external opening close to the fistula, dissect the external sphincter fistula to the intersphincteric groove by tunneling technique, resect the lateral free fistula) and LIFT group (33 cases). Clinical parametres before and after operation were compared, and results of pelvic electromyogram (EMG) and anorectal manometry three months after operation were analyzed to evaluated anal function.

RESULTSThe operative time, pain score, hospital stay, and healing time were not significantly different between the two groups (all P>0.05). During the median follow-up of 12 months (3-20 months), the healing rate in modified-LIFT group was 83.8% (31/37), which was significantly higher than 60% (20/33) in LIFT group (P=0.029). After operation, 4 patients had persistent unhealed wound, 2 recurred in modified-LIFT group, while 8 patients had persistent unhealed wound, and 5 recurred in LIFT group. No patients developed anal incontinence. By the pelvic EMG and anorectal manometry 3 months after operation, the duration of motor unit potential, occurrence of simple phase, mean resting pressure and maximun squeeze pressure were not significantly different.

CONCLUSIONModified-LIFT procedure for the management of simple transsphincteric perianal fistulas is a simple and effective operation with higher healing rate and similar anal function as LIFT.

OBJECTIVETo explore the feasibility and clinical significance of the detection of serum neutrophil gelatinase-associated lipocalin (NGAL) in human colorectal cancer.

METHODSLevels of NGAL in serum samples from 133 healthy people, 125 colorectal polyps patients and 100 colorectal cancer patients respectively were determined by sandwich ELISA assay. Relationship of NGAL level with clinicopathological features of colorectal cancer patients was analyzed. The optimal cut-off value of serum NGAL for diagnosing colorectal cancer was determined by ROC curve and compared with CEA and CA19-9. Univariate and multivariate analyses were performed to examine the relationship of NGAL level with the prognosis of patients with colorectal cancer.

RESULTSThe median serum NGAL protein level in 100 colorectal cancer cases was 67.96 (53.30-79.86) μg/L, significantly higher than that in healthy people and colorectal polyps patients. The differences were statistically significant (all P<0.01). Serum NGAL protein level was significantly associated with tumor diameter, TNM stage, lymph node metastasis and vascular involvement (P<0.05). The optimal cut-off point of serum NGAL protein level for diagnosing colorectal cancer was 49.78 μg/L, and the sensitivity and specificity were 88% and 81% respectively. As for colorectal cancer patients with stage I, the sensitivity of serum NGAL (78.9%) was significantly higher as compared to CA19-9 (31.6%) and CEA (36.8%); as for those with stage II, the sensitivity of serum NGAL(88.0%) was also significantly higher compared to CA19-9 (48.0%) and CEA (52.0%). Kaplan-Meier analysis showed that patients with positive NGAL (≥49.78 μg/L) had worse survival than those with negative NGAL (P=0.002). Multivariate analysis showed that NGAL was an independent prognostic factor (HR=2.060, 95%CI:1.023-4.150, P=0.043).

CONCLUSIONSNGAL can be served as the novel malignant biological phenotype marker for human colorectal cancer and can be used for the risk stratification. NGAL may be an independent prognostic factor in colorectal cancer.
