Objective To investigate the responses of neurons and astrocytes within rat′s spinal trigeminal nucleus(Sp5C) following nocuous pain stimulation induced by subcutaneous formalin injection into the unilateral upper lip. Methods By means of anti\|phospholipase(PLC),anti\|Fos protein and anti\|glial fibrillary acidic protein(GFAP) immunohistochemical method,the distribution of reactive neurons and astrocytes in the Sp5C was observed at different time after formalin injection. Results No immunohistochemical staining was found in normal rat Sp5C.After formalin injection,PLC like immunoreaction(\|LI),Fos\|LI and GFAP\|LI were found in astrocytes while PLC\|LI and Fos\|LI in neurons.The labeled astrocytes and neurons showed similar distribution and close relationship.PLC\|LI and Fos\|LI were found earlier than that in neurons.Conclusion\ The results suggested that the astrocytes in the Sp5C might participate in pain modulation in CNS and actively regulate neuron′s function.

Objective To evaluate the safety and feasibility of step-by-step balloon dilatation combined with contineous biliary drainage in treating benign biliary-enteric anastomosis stricture.Methods The clinical data and imaging materials of 49 patients with benign biliary-enteric anastomosis stricture,who were admitted to authors' hospital during the period from January 2008 to March 2014 to receive treatment,were retrospectively analyzed.Before treatment,the diagnosis of benign biliary-enteric anastomosis stricture was confirmed in all patients by color Doppler ultrasound,MRI and/or contrast-enhanced CT scan,endoscopic or DSA-guided anastomosis biopsy.Among the 49 patients,23 patients (study group) were treated with percutaneous transhepatic step-by-step balloon dilatation (the diameter of used balloon was 8 mm initially,then 10 mm balloon was used in the second month,and 12 mm balloon was used in the third month) together with contineous biliary drainage (lasting for 6 months);26 patients (control group) were treated with single percutaneous transhepatic balloon dilatation (balloon diameter of 6 mm or 8 mm) plus biliary drainage (lasting for 6 months).The improvement of clinical symptoms,the incidence of postoperative complications,and the anastomotic patency rate were compared between the two groups.Results Technical success was obtained in all patients.No procedure-related complications,such as biliary tract hemorrhage and perforation,occurred.One week after the treatment,the difference in bilirubin level between the two groups was not statistically significant (P>0.05).Although the difference in 3-month anastomotic patency rate between the two groups was not statistically significant,the 6-month,12-month and 24-month anastomotic patency rates of the study group were significantly higher than those of the control group (P<0.05).Three patients in the study group developed recurrent jaundice at 11.2,14.3 and 17.6 months after treatment respectively;MRI and contrast-enhanced CT scan confirmed the diagnosis of anastomotic stricture recurrence,and balloon dilatation together with drainage tube placement had to be carried out again.In the control group,16 patients developed recurrent jaundice within 3.1-17.1 months after balloon dilatation management,among them one patient died of disseminated intravascular coagulation and the remaining 15 patients received balloon dilatation together with drainage tube placement again.Conclusion For benign biliary-enteric anastomosis strictures,step-by-step balloon dilatation combined with persistent biliary drainage is a safe and effective minimally-invasive treatment.

Objective To provide data support for the prevention and control of melioidosis by analyzing epidemiological characteristics of melioidosis bloodstream infection and antibiotic resistance of its pathogen in Hainan Province from 2012 to 2021. Methods Data was collected from Hainan Antimicrobial Resistance Surveillance System, and WHONET 5.6 software was used to merge and analyze data. Results The case numbers of melioidosis bloodstream infection showed an increasing trend year by year from 2012 to 2021. The ratio of male to female patients was 4.6∶1, with 347 cases (58.91%) of patients aged 40-<60, the age group with the highest incidence. The number of cases from July to November were 424 cases (72.0%). Haikou and Sanya reported the largest case number, with 261 and 116 cases respectively. But there were no case reported from central area including Chengmai, Tunchang, Qiongzhong and Baoting. Burkholderia pseudomallei strains were isolated from both blood and other specimens in 105 of the 589 patients, with respiratory tract and wood specimens being the sites with the highest number of strains isolated other than blood; the resistance rates of Burkholderia pseudomallei to five antibiotics showed no obvious trend of change, with the lowest resistance rate to imipenem among the five drugs at 0.6%, followed by ceftazidime at 2.2%. Conclusion During the typhoon season, elderly, middle-aged male in coastal areas should pay attention to avoid or reduce their contact with mud and water. For patients with melioidosis bloodstream infection, imipenem or ceftazidime should be selected as early as possible for initial treatment.

Objectives Todynamicallyobservethechangesofhemodynamicparametersinpatients with severe stenosis of unilateral middle cerebral artery (MCA)by transcranial Doppler ultrasound (TCD) andtoevaluateandanalyzetherelatedfactorsforinfluencingthestenoticprocess.Methods Atotalof 113 consecutive patients with severe stenosis of unilateral MCA screened by TCD and confirmed by computed tomography angiography (CTA)and digital subtraction angiography (DSA)were enrolled retrospectively. They were divided into either a progressive group (n =43 )or a non-progressive group (n=90)according to the variation of MCA hemodynamic parameters. The effects of age,sex,major risk factors for cerebrovascular disease,clinical symptoms,clinical medication,and drug compliance on the stenotic process were documented and analyzed. Results (1)The comparison of detection rate of the risk factors for cerebrovascular disease:The patients with a history of smoking (72. 1%[n=31])in the progressive group was significantly higher than that (51. 1%[n=46])in the non-progressive group (P=0.022). The period of smoking of the patients in the progressive group were longer than that in the non-progressive group (28 ± 12 years vs. 21 ± 10 years,P=0. 011). (2)Comparison of MCA hemodynamic parameters:The distal pulsatility indexes of MCA stenosis at the first diagnosis in the progressive group were all lower than those in the non-progressive group (0. 66 ± 0. 10 vs. 0. 70 ± 0. 13;t= -2. 096,P=0. 038),and the distal pulsatility indexes of MCA stenosis at the end point in the patients of the progressive group were lower than those in the non-progressive group (0. 61 ± 0. 15 vs. 0. 74 ± 0. 15). There were significant differences (t=-2. 718,P= 0. 008). The peak systolic velocity (PSV)of the progressive MCA stenotic segments at the end point in 10 patients of the progressive group was higher than that in the non-progressive group (299 ± 23 cm/s vs. 244 ± 50 cm/s,t=3. 437;P=0. 001),while PSV of MCA in 33 patients with occlusion in the progressive group were significantly lower than those in the non-progressive group (56 ± 18 cm/s vs. 244 ± 50 cm/s,t= -20. 905;P=0. 000). (3)The regular medication:The patients using statins (atorvastatin calcium)were significantly lower than those of the non-progressive group (2. 3%[n=1] vs. 54. 4%[n=49],χ2 =33. 690;P<0. 01). (4)During the follow up period,the recurrence rates of transient ischemic attack and stroke of the progressive group were significantly higher than those of the non-progressive group (27. 9%[n=12]vs. 6. 7%[n=6],32. 6%[n=14]vs. 2. 2%[n=2];all P<0.01). (5)Multivariate Logistic regression analysis showed that smokers (OR,4. 403,95%CI 1. 094-14.017),cerebrovascular event recurrence (OR,10. 648,95%CI 2. 530 -41. 261),and irregularly taking statins (OR,5. 675,95%CI 1. 631-152. 740)were all closely associated with the progress of severeMCAstenosis.Conclusion EvaluationofthehemodynamicchangesofsevereMCAstenosiswith TCD follow up study can be used as an important basis for clinical assessment of the outcomes. Stop smoking and regularly taking statins may help to delay the progress of MCA stenosis.

Objective To understand the molecular aberration at whole genomic level,CGH (comparative genomic hybridization) was used to investigate genetic abnormality in lung cancer.Methods Comparative genomic hybridization was performed in 17 cases to detect the global genomic aberration in cancer tissue cells.Results All of 17 cases detected by CGH showed chromosomal aberrations.The average numbers of chromosomal gains and losses in each case were 7.0 and 4.8 in NSCLC and 8.4 and 9.6 in SCLC,respectively.The frequency of gains and losses on chromosome had no significant differences between NSCLC and SCLC.The frequencies of gains on chromosomal arms 3q24 -28 and 11q13(58.3% and 58.3% ) in NSCLC were significantly higher than that in SCLC(0% and 0% ) ( P <0.05 and <0.05,respectively).Conclusions The cytogenetic aberration generally existed in lung cancer cells.Several regions ( more than one) of chromosomal aberration were involved in the carcinogenesis of NSCLC and SCLC.The regions and frequencies of chromosomal aberration in NSCLC were somewhat different from that in SCLC,which might result in the different biological behavior of the two types of lung cancer.The chromosomal aberration might be served as a marker to differentiate the two types of lung cancer.
