Objective To investigate whether intranasal dexmedetomidine prevents the emergency delirium after sevoflurane-based anesthesia (ASA) in children.Methods Ninety children (ASA I,2 to 7years) undergoing elective tonsillectomy with or without adenoidectomy,were randomly divided into group D1 (intranasal dexmedemidine 1.0 μg/kg),group D2 (intranasal dexmedemidine 0.5 μg/kg),and group NS (intranasal normal saline).Anesthesia was induced with sevoflurane (30 min after intranasal administration) and maintained with sevoflurane in 50/50％ O2/N2O.Heart rate (HR),blood pressure (BP),and hemoglobin oxygen saturation (SpO2) were monitored before intranasal administration to 2 hours after extubation.Time of operation and extubation were recorded.Pediatric anesthesia emergence delirium (PAED) scale,Modified Children's Hospital of Eastern Ontario Pain Scale (m-CHEOPS) Pain scale and the adverse effects were observed.Results The PAED scales of group D1 and Group D2 were significantly lower than group NS.No significant differences were found in hemodynamic and respiratory variables,pain scale,time of extubation and adverse effects among three groups.Conclusions Intranasal dexmedetomidine decreased the severity of emergence delirium after sevoflurane-based anesthesia in children without prolonging the time to extubate and affect hemodynamics and respiratory variables.

With the rapid development of general anesthesia technology and the occurrence of new types of inhalation and intravenous anesthetics,safety and comfort requirements of general anesthesia become increas-ingly higher. Therefore,emergence agitation and its adverse consequences gradually receive more and more atten-tion . Thus the etiology and prevention of emergence agitation is an important issue in pediatric anesthesia at pres-ent. In recent years, some achievement has been made in emergence agitation following general anesthesia in children. This article will summarize the related factors,possible mechanisms and prevention strategics of pediat-ric emergence agitation.

There has been no detailed reiport on the changes of the activity of serum glycylproline dipeptidyl aminopeptidase (GPDA) in patients with pancreatic career.Tn this paper,the serum level of GPDA was measured in 166 cases with various malignant and benign gastrointestinal diseases and 60 normal controls.It was found that the serum GPDA activity in patients with pancreatic cancer was 101,02?75.84u/L and significantly higher than that in the patients with pancreatitis and in the normal controls.There was a statistically significant difference of the GPDA activity value between the patients with malignant and benign pancreatic diseases.The elevation of GPDA activity was more marked in those patients with cancers in the head of the pancreas.In addition,the elevation of GPDA activity was dependent on the differentiation of cancer cells but not on the size of cancers.Significantly higher level of GPDA was also found in patients with hepatic carcinoma and carcinoma of ampulla of vater but significantly lower level in patients with gastric cancer.It is believed that the determination of serum GPDA activity might be helpful for the diagnosis of pancreatic cancer.

The sera of 40 normal controls,61 cases of various malignant diseases except pancreatic cancer,53 cases of various henign diseases,and 33 cases of pancreatic cancer were examined with ELISA to determine the serum level of pancreatic cancer-associated antigen(PCAAc).Its normal value was 12.59?6.34 mg/L(x?s),and the value was 57.25?82.93 mg/L in the pancreatic cancer group,which was significantly higher than the normal value and that of the other malignant disease group(P

Objective To compare the clinical pathological characteristics in young and old patients with colorectal cancer (CRC) and investigate their relationship with prognosis. Methods A retrospective review was made in 68 CRC patients less than 35 years old and 322 CRC patients older than 65 treated in our hospital from July 1993 to July 2003. Their clinical manifestation, pathological feature, Dukes staging, misdiagnosis rate and results of following-up were compared. Results The main manifestation in young group was abdominal pain (69.1%), but in old group was hemafecia or mucous bloody stools (53.7%). The ratio of poorly differentiated neoplasm was obviously higher in young group (48.5%) than in old group (20.5%) (P

OBJECTIVETo investigate the correlation between the pathogeneses of diarrhea-pre- dominant irritable bowel syndrome (D-IBS) complicated functional dyspepsia (FD) patients of Gan-stagnation Pi-deficiency Syndrome (GSPDS) and symptoms, psychological states, and gastrointestinal hormones.

METHODSA total of 111 patients with confirmed D-IBS complicated FD of GSPDS were recruited as the treated group by using Rome III standard and Chinese medical syndrome standard. And 30 healthy volunteers were recruited as the control group. The general condition, scoring for digestive symptoms, and the distribution of GSPDS subtype of all subjects were recorded by a questionnaire, and assessed by Symptom Checklist (SCL-90; a software for psychological test developed by Beijing Huicheng Adult Cor- poration). Meanwhile, plasma levels of 5-hydroxytryptamine (5-HT), somatostatin (SS), vasoactive intestinal peptide (VIP), endothelin (ET), interleukin 10 (IL-10), and interleukin 12 (IL-12) were measured in all subjects.

RESULTS(1) The subtype of D-IBS complicated FD of GSPDS was dominant in Pi-qi deficiency type (51/111,45.9%),Pi yang deficiency type (34/111,30.6%), and GSPDS. There was no statistical difference in the scoring of digestive symptoms among the 3 subtypes (P >0.05). (2) Compared with the control group, the anxiety factor score and the total score significantly increased in all three subtypes of D-IBS complicated FD of GSPDS, and the depression score of Pi yang deficiency type and Gan-depression type also significantly increased (P <0.05, P <0.01); the depression score of Gan-depression type was significantly higher than that of the Pi-qi deficiency type (P <0.01). Plasma 5-HT levels were obviously lower in D-IBS complicated FD patients of GSPDS accompanied with anxiety or depression than in those with no obvious psychological abnormalities, and VIP and IL-10 levels were significantly lower than those in the control group (P <0.05). Plasma VIP levels were also obviously lower in D-IBS complicated FD patients of GSPDS accompanied with anxiety or depression than in those with no obvious psychological abnormalities (P <0.01), and SS levels were significantly lower than those in the control group (P <0.05). There was no statistical difference in plasma ET or IL-12 levels in each patient group, when compared with the control group (P >0.05). (3) Compared with the.control group, plasma 5-HT levels significantly increased, plasma VIP and IL-10 levels significantly decreased in ach subtype of D-IBS complicated FD patients of GSPDS (P <0.05, P <0.01), and no significant change of SS, ET, or IL-12 occurred (P >0.05). Besides, plasma 5-HT levels were significantly higher in Gan-depression type than in Pi yang deficiency type, VIP levels were lower in Gan-depression type than in Pi-qi deficiency type (all P <0.05).

CONCLUSIONSGan stagnation and Pi deficiency were dominant in D-IBS complicated FD patients of GSPDS. Psychological abnormalities, increased plasma 5-HT levels, and decreased plasma VIP levels were closely correlated with Gan stagnation subtype, which provided some reference for looking for objective indicators of Chinese medical syndromes in treating D-IBS complicated FD patients of GSPDS.

Objective To compare the characteristics of hMPV infection in BALB/c and SCID mice.Methods BALB/c and SCID mice were infected intranasally with GFP-rhMPV,and sacrificed on day 3,5,7,9 and 14 post inoculation.Heart,liver,spleen,lungs,kidneys and brain of the animals were used for viral isolation,titration,pulmonary histopathology and detection of GFP-hMPV mRNA expression by RT-PCR and real-time PCR.Results Live viruses were successfully isolated from the lungs of infected mice.Viral titers peaked on the 5th day post inoculation.Viruses remained to be detectable on the 14th day post inoculation in SCID mice,but not in BALB/c mice,whereas genomic RNA of GFP-rhMPV was detectable by PCR targeting F gene in infected BALB/c mice.Live viruses were not able to be isolated from heart,liver,spleen,kidney and brain,neither was genomic RNA of hMPV able to be detected on the 5 th day post inoculation by RT-PCR and real-time PCR.Histopathology of lungs was characterized by interstitial pneumonia on 5 days post inoculation.Lung pathology score of BALB/c mice group was slightly lower than SCID,and the difference was not statistically significant.Conclusion GFP-rhMPV can only replicate in the immunocompetent and immunodeficient mouse lungs,but not in other organs.As compared to that in BALB/c mice,the viral replication appears to be more efficiently and for longer time in SCID mouse lungs probably due to the absence of host cellular and humaral immunity,but this does not necessarily result in more severe pathological lesion.
