Objective To evaluate the effects of intraoperative intraperitoneal chemotherapy with sustained release 5-fluorouracil for implantation(5-Fu SRI) for the treatment of locally advanced colon cancer. Methods A total of 70 patients with locally advanced primary colon cancer(T4N0M0 and stage Ⅲ) undergoing radical resection were divided into treatment group(n=36,intraoperative intraperitoneal chemotherapy with 600mg 5-Fu SRI)and control group(n=34,intraoperative intraperitoneal flushing with 1000mg 5-fluorouracil injection). Both groups received the same postoperative chemotherapy regime.The 2-year survival rate,local recurrence rate and distant metastasis rate were retrospectively analysed. Results The 2-year survival rate and local recurrence rate were more favourable in treatment group than those in control group(P0.05). Conclusion Intraoperative intraperitoneal chemotherapy with 5-Fu SRI may decrease postoperative local recurrence rate and increase 2year survival rate.

Objective To investigate the value of left ventricular function in patients with chronic pulmonary heart disease(CPHD) using strain rate imaging (SRI).Methods This study included 64 patients with CPHD (30 patients with compensatory function and 34 with decompensatory function) and 30 normal control.Peak systolic strain rate (SRs),peak early diastolic strain rate (SRe) and peak late diastolic strain rate (SRa)of left ventricular basal and middle segments were measured,and then mean peak strain rate (mSR) was calculated.The above digital parameters were analyzed compared with the conventional echocardiographic indices.Results The indices (mSRs,mSRe,mSRe/mSRa)in CPHD were reduced and mSRa increased as compared with those in controls (all P=0.000).And the above indices showed the same change when decompensatory group was compared with compensatory group (P=0.000,0.038,0.015,0.001).Negative correlation was noted between LVEF and mSRs in patients with CPHD (r=0.75,0.82;P=0.000).Conclusions LVEF is negatively related with mSRs in CPHD patients.mSRs can reflect the status of left ventricular function.SRI is a more sensitive tool in quantitative evaluation of left function of CPHD.

Objective:To investigate the change in myogenin expression at different time in long-term denervated human posterior cricoarytenoid muscles(PCAMs),so as to provide a theoretical basis for timing of reinnervation.Methods: Thisty-eight specimens of denervated human PCAMs were divided into 4 groups according to the period of denervation: 6-12 months denervation group(n=12),1-2 years denervation group(n=10),2-3 years denervation group(n=8),and over 3 years denervation group(n=8).Another 12 specimens of normal PCAMs served as control.The patients in all groups were age-and sex-matched.The expression of myogenin protein and mRNA was studied using immunofluorescence staining and real-time PCR analysis,respectively.Results: Immunofluorescence staining showed that the positive myogenin expression was mainly!found in the myonuclei of PCAMs with a denervation period less than 3 years;no positive staining was found in the myonuclei of control group.The expression of myogenin in myonuclei and the ratio of positive cells were up-regulated in the 6-12 month denervation group compared with those in the control group;the expression and the ratio peaked in 1-2 years denervation group and decreased again in the 2-3 years denervation group,but was still significantly higher than those of the control group(all P

Objective:To study the morphological changes of posterior cricoarytenoid muscles(PCM) in patients with long-term denervation of recurrent laryngeal nerve(RLN),so as to provide theoretical evidence for repair of recurrent laryngeal nerve at advanced clinical stage.Methods: Thirty-eight patients with damaged RLN were divided into 4 groups according to the duration of their RLN damage: 6-12 months group(n=12),1-2 years group(n=10),2-3 years group(n=8),and over 3 years group(n=8).Twelve subjects with normal PCM served as control.Trichrome Masson staining and imaging analyzing system were used to quantitatively analyze the transverse section areas of myofibers,collagen fiber and connective tissues.SDH and AchE staining and cell counting method were used to analyze changes of two kinds of myofibers and motor end plate numbers at different times after denervation of recurrent laryngeal nerve.Results: The transverse areas of myofibers gradually decreased and those of collagen fibers gradually increased with the prolongation of denervation;the difference was significant between different groups(P

Objective To investigate the pathogenesis, distribution of the pathogens and resistance pattern of nosocomial pneumonia in patients with diseases of central nervous system(CNS).Methods Bacterial typing was conducted on the 59 strains separated from the sputum of 59 patients of nosocomial pneumonia with CNS diseases in our hospital in 2002.MIC drug sensitive test in vitro was conducted with the most common 15 antibiotics.Results The most common pathogens of nosocomial pneumonia in the diseases of CNS were:Staphylococcus aureus 23.7%,Pseudomonas aeruginosa 22.0%,Acinetobacter baumannii 18.6%,Klebsiella pneumoniae 8.5% Xanthomonas maltophilia 6.8%?According to the drug sensitive test,antimicrobial-resistant gram-negative bacilli were increasing.None of the vancomycin-resistant MRSA variant was seen.Conclusion The risk factors of nosocomial pneumonia in the diseases of CNS are long hospital stay,respiratory tract invasive operation and unreasonable antibiotic therapy.The most common pathogens were Staphylococcus aureus,Pseudomonas aeruginosa,Acinetobacter baumannii,Klebsiella pneumoniae and Xanthomonas maltophilia.Effective and infection-control procedures,surveillance systems and appropriate antimicrobial selection are key methods in limiting nosocomial pneumonia and antimicrobial-resistant pathogen occurrence.

Objective To explore the incidence rate, total incidence numbers and possible impacting factors of non-motor symptoms (NMSs) in Parkinson's disease (PD). Methods The NMS questionnaire (NMS Quest) was used to investigate 131 out-patients diagnosed with PD, and the prevalence of each item, the total NMS numbers and their relationships with clinical features were assessed. Results All of the patients, who were distributed in every stage of PD, had NMSs and each case with 11 items on average. Autonomic symptoms such as nocturia and constipation were the most frequent ones. The patients over 65 versus less than 65 years old had a higher prevalence in a number of items such as olfactory disturbance, dysphagia and constipation. At the same time, the rigidity subtype patients had a higher prevalence in depression items than the tremor subtype ones.The total number of NMS was positively correlated with course of disease, age, UPDRS score and Hoehn & Yahr (H&Y) stage. Conclusions NMSs are common among PD patients. While the prevalence of each item may vary with different clinical features, the total number of NMS is increased with the severity of PD. More attention should be paid to the diagnosis and rational treatment of the NMSs.

Objective To explore the relative factors on delayed encephalopathy after acute carbon monoxide poisoning(DEACMP)and the signifiance of P 300 for judging the severity and prognosis of DEACMP.Methods Thirteen aspects such as contact time with carbon monoxide (CO)?coma time et al were analysed between 44 patients with DEACMP (DEACMP group)and 42 patients with acute CO poisoning but without DEACMP (ACMP group). P 300 s were studied in the patients with P 300 as compared with the patients had just caught acute CO poisoning (DEACMP group).and 44 normal controls (NC group).Results There was extremely significant difference in contact time with CO,coma lasting time,treatment time with hyperbaric oxygen,age,complication ( P

Objective To observe the preventive effect of mannatide on infection and relapse of idiopathic thrombocytopenic purura(ITP).Methods One hundred and twenty children with ITP were randomly divided into mannatide treatment group and prednisone control group.Control group venous dexamethasone of 3 d;then treated by prednisone.Treatment group added mannatide tablets for 1 month.The rates of remission clinical blood,platelet,control time,complicated infection and relapse rates were observed.The levels of plasma immunoglobulin(Ig)G,IgA,IgM were determined before and after mannatide treatment.Results The rate of clinical blood,platelet,control time,infection time was not different in 2 groups.The rates of infection complicated and relapse were all significant lower than that in control group.The plasma IgG,IgA significantly increased than that in control group.The plasma IgM had no significant difference.Conclusion Vaccine therapy can be helpful in protecting and decreasing infection,diminishing relapse of children with ITP,and improve the level of IgG,IgA,and thus improve their immune function.

Objective To investigate the expression of homeobox gene MSX-2 during cranial suture fusion of SD rats and discuss its significance. Methods SD rats aged 1, 2, 5, 8, 12, 15, 18, 22, 30 and 45 days were selected, and immunohistochemistry and Real-time PCR were employed to localize and quantify the expression of MSX-2 in different regions of cranial sutures. Results MSX-2 expressed in calvarial suture tissues including the extreme ends of the osteogenic fronts and the underlying dura mater. The expression of MSX-2 was low in posterior frontal suture (PF) and sagittal suture (SAG) from postnatal day 1 to day 8 before the initiation of suture fusion, while it was higher in PF than in SAG from postnatal day 12 to day 22 after the initiation of PF suture fusion. The expression of MSX-2 significantly declined in PF and was moderately higher than that in SAG from postnatal day 30 to day 45 after the initiation of suture fusion. Conclusion There is different expression of MSX-2 in PF and SAG during different suture fusion periods, which suggests the expression of MSX-2 may participate in the regulation of cranial bone development and the fusion of cranial sutures.

OBJECTIVETo evaluate the efficacy and safety of Yigan Fupi Decoction (YFD) in the treatment of irritable bowel syndrome with diarrhea (IBS-D) patients.

METHODSA randomized controlled clinical trail was carried out in patients with IBS-D. All patients were randomly assigned to the treatment group (58 cases, treated with YFD) and the control group (58 cases, treated with Pinaverium Bromide Tablet). The treatment course was 4 weeks for all patients. The total effective rate, the stool property and state, the quality of life (QOL), and TCM syndrome efficacy were assessed by IBS bowel symptom severity scale (IBS-BSS), IBS defecation state questionnaire (IBS-DSQ), IBS quality of life questionnaire (IBS-QOL), and traditional Chinese medicine pattern curative effect scoring system (TCM-PES) before and after treatment.

RESULTSThere was no statistical difference in the total effective rate between the two groups (82.76% vs. 77.59%, P > 0.05). The treatment group was superior in the total IBS-BSS integral to the control group (P < 0.05). The total effective rate of improving the stool property was better in the treatment group than in the control group (81.03% vs. 72.41%, P < 0.05). Besides, the number of days for emergent defecation among 10 days was less in the treatment group than in the control group (P < 0.05). The improvement of the total IBS-QOL integral and the total integral of TCM syndrome were better in the treatment group than in the control group (P < 0.01). The total effective rate of TCM-PES was better in the treatment group than in the control group (84.48% vs. 70.69%, P < 0.05).

CONCLUSIONYFD was effective in the treatment of IBS-D patients of Gan-qi invading Pi syndrome, and could effectively relieve bowel symptoms, improve the stool property and the defecation frequency, elevate their QOL, and attenuate Gan-qi invading Pi syndrome with favorable safety and compliance.
